Bigger headers will definatley help, you should be low 11's with head flow like that (if the port design is good).

I would try jetting for best MPH and see what you get instead of A/F.

More convertor should help the 60's which will speed you up.

Do you run an air cleaner? Im asking only because on my holley 950hp the air cleaner stud hole goes all the way though the base plate if you dont block it you will have a serious vacuum leak.

biltit--It would be nice to run bigger headers, just havent had good luck finding ones that will fit the chassis with a big block olds in it. I have been told that ones from the 64-72 A body will fit, but I'm not 100% sure and I have also heard that ones from a 65-76 delta 88 would fit with no modifications, but I just need to make sure before anything like that would be ordered and then find myself dinging all the tubes. New converter is to be in sometime towards the end of the week so maybe I'll get lucky to make a pass or two if the weather holds out.

sc racing--I have ran the car with an air cleaner and without an air cleaner and it didnt seem to make a difference. I did check tho to make sure that the air cleaner stud hole wasnt the whole way through like yours is.

Thanks again everyone!....anyone still got thoughts left?
